How to: Jack RIB off Trailer?

georgeirl · 15 February 2017, 11:34

As above, I need to antifoul my rib, it was done already by the PO and not interesting in trying to go back to gel coat for now, maybe at some point in the future.

My boat is a 8M ribtec with inboard diesel = not light!

Is it ok to jack it up and block it at 2/3 points on the hull while I'm antifouling her. Will that put excessive stress on the hull to be supported by a couple of points vs to the 30+ rollers that as currently supporting her!

Naturally if anyone has any other suggestions i'm open to them! New to this so any tips welcome.

Thanks,

George

have you tried talking to a local marina for a lift if thier not busy you might be able to give it a coat while they wait or put it on a cradle for you better than laying under a trailer there will be a cost but much easier & safer.

My hard cruiser which is 38ft & 8.5tonnes gets lifted onto 3 blocks along the keel and two stabilising blocks at the stern either side this is how she spends every winter and it's fine.

Take a walk around any marina yard and you'll see almost every motor boat blocked up in this manner
I'm sure your rib will be absolutely fine in the same manner
When we antifoul it we do everything but the few places where there are blocks then move the blocks and do the missed bit

Thanks, i assumed it would be fine but its great to get it confirmed before i end up with a block shaped hole in my hull! Standing on the side of caution and I know when it comes to these things guys on here have done it all so worth checking. No substitute for experience!

Jeff,

No marinas around here with a permanent lift. Crane hire when needed. Generally crane lifts are April / May , Sept / Oct and thats when we get discounts for multiple lifts on the same day.

If was to hire a crane just to do this it would be a minimum of 300 and I can spend a lot of time crawling under a boat for that! It it was less than 100 i would agree with you and get her lifted!

Now in my sixtys I tend to look for the easy option but as you say not always Available I was lucky when I needed mine lifting I had a dolly to push it on and the farm has a four post car lift free to use hope you get sorted nothing wrong with jacking her up as beamishken has said most do

Plenty of videos on Youtube on how to get RIB off a trailer onto blocks.

georgeirl · 15 February 2017, 21:39

Mike... You would think so. Found a few on hard boats but not ribs!

I saw that one! Much smaller.

mikew4 · 15 February 2017, 22:01

Just use a load of old car tyres as cushions.

georgeirl · 15 February 2017, 22:03

I really like the trailer jacking idea from the other thread you sent me. Sorry I did search but didn't find that thread!

No worries. Glad to be of help. Hope it works out for you !

Mike.

if you have a set of car ramps you could back your trailer up on them and lift the front with the jockey wheel and jack to give quite a bit of height and just move the boat back a tad to paint where the rollers are when its back on the ground hitched to the car to finish, that would save you jacking the hull its self if it bothers you a bit.

SteveHall · 16 February 2017, 10:11

I tried with car ramps, and the trailer wouldnt go up them - it just kept dragging the ramps along the floor, or firing them out.

georgeirl · 16 February 2017, 10:37

For reference --- she is not small! I don't think ramps would work with the twin wheels!

BTW she was been cleaned up a lot since!Must get new pics soon

Very nice - I've got a 9m Ribtec probably of a similar vintage with the same engine box and console.

I actually don't know the exact vintage, if there anything on the vessel that would hint / point to it?

nice big old girl

Mine's a 2004 model. There should be a HIN number stamped into the transom, possibly with a small plate over it as well. Mine is located on the starboard side, underneath the tube mounting on the transom. I forget if it contains a sequence that directly correlates to build year, but Ribeye/Ribtec may be able to provide some limited detail (although from my previous conversations with them, I understand most of the records of the Ribtec builds seem to have gotten lost in the changeover).
